Selecting a messaging protocol for transmitting data in connection with a location-based service

A non-transitory computer-readable medium storing instructions that, when executed by one or more processors of a computing system, cause the computing system to:

• receive, from a first computing device, a request for a transport service, the request including (i) a user identifier associated with a first user of the first computing device, (ii) contact information associated with a second user, and (iii) a pickup location information;
• make a determination whether a user account associated with the second user is stored in a user database using the contact information retrieved from the request for the transport service;
• based on the determination, select a messaging protocol to transmit data to a second computing device associated with the contact information;
• and
• transmit, from the computing system, a message corresponding to the transport service to the second computing device using the selected messaging protocol.

A system, comprising:

• one or more communication interfaces;
• one or more processors coupled to the one or more communication interfaces;
• and
• one or more memory resources storing instructions that, when executed by the one or more processors, causes the system to:
• receive, from a first computing device via the one or more communication interfaces, a request for a transport service, the request including (i) a user identifier associated with a first user of the first computing device, (ii) contact information associated with a second user, and (iii) a pickup location information;
• make a determination whether a user account associated with the second user is stored in a user database using the contact information retrieved from the request for the transport service, the user database being stored in the one or more memory resources or in another memory resource accessible by the system;
• based on the determination, select a messaging protocol to transmit data to a second computing device associated with the contact information;
• and
• transmit, from the computing system via the one or more communication interfaces, a message corresponding to the transport service to the second computing device using the selected messaging protocol.
